Ditch the Vata Pitta Kapha Dosha approach, pass by the Panchmahabhuta and use the 20 gunas as the best way in self-care.
The Dosha's are the most popular used terms from Ayurveda but they are a categorizing system and have been misapplied as energetics themselves. It all began thousands of years ago when the science of Ayurveda was taken from an oral tradition and written down in the Vedas.
Ayurveda was changed and adapted over time in different regions of India and into Tibet.
Ayurveda was 'cleaned up' to make it more civilized! It was systematized into a science and pruned from what appeared to be a pagan type ritual based way to a healthy body-mind-environment. According to Dr Rama Prasad Ayurveda was marketed to make it more appealing and in the process the Doshas became sellable concepts which have seriously stuck!
The Doshas were not intended by the RIshis to be the main approach of Ayurveda, but rather a way to talk about all things dry, rough, hot, slow etc. We do ourselves a disservice and easily become confused when we label ourselves with them constitutionally. We bump into their limitations constantly and this approach doesn't take into account the natural flexibility our bodies have to adjust during a day, or the way we present Vikruti needs.
But what about my Doshic constitution (Prakruti)?
Agni = digestive enzymes and capacity.
